> When spark runs in mesos fine-grained mode, mesos slave launches executor with # of cpus
and memories. By the way, # of executor's cores is always CPU_PER_TASKS as same as spark.task.cpus.
If I set that values as 5 for running intensive task, mesos executor always consume 5 cores
without any running task. This waste resources. We should set executor core as a configuration
variable.
